Threadless Stems for 31.8mm Handlebar

31.8mm stems (handlebar clamp diameter) are the "oversized" stems becoming the standard on high quality road and mountain bikes. Road and mountain stems are therefore technically interchangeable, but a stem's intended use must be kept in mind: a road or XC stem will not be strong enough for freeride or downhill use.
